Triumph Motorcycle Restoration - Pre-Unit, takes a thorough look at what is required to restore a Triumph 650cc twin built before 1963. The book includes two, start-to-finish restorations: one done on a 1959 Bonneville and the other on a 1956 TR6. Hands-on sequences make up the heart of this book. Abundant color photographs show the complete assembly of both bikes, from installation of the swingarm and chassis parts to the attachment of the fenders and gas tank. Author and experienced Triumph mechanic, Garry Chitwood, explains the right and wrong way to assemble these bikes, and the little things that separate an amateur rebuild from a proper and award winning restoration. More than just a motorcycle assembly manual, Triumph Motorcycle Restoration, includes the overhaul and assembly of a 650cc twin engine, and the four-speed transmission. Both operations are explained and illustrated from beginning to end. Rather than try and explain the minute differences that separate different models and years, the new Triumph Motorcycle Restoration - Pre-Unit book offers a series of color plates in the middle of the book that provide left and right side views of most of the significant models sold in the 1950s and early 1960s. Triumph Motorcycle Restoration - Pre-Unit, offers the Triumph motorcycle enthusiast 144 pages and over 450 photos explaining how to buy, build and restore a Triumph 650cc twin manufactured before 1963.
